Ps2 backups

[Pimpin]

I just got a cd burner, and tried to make a copy of some of my ps2 games. I've tried cdrwin, nero, clone cd, and my ps2 won't read any of the cds. I even downloaded some ps2 burning for dummies and can't get it to work like that. My system is a celeron about 500mhz 128 megs of ram a lite on cd burner 12x10x32x. Is there an easy way to do this without getting a mod chip. Help Please
